Dr. Bowman: Precautionary Strategies for Reducing Worker Exposures to ELF Magnetic Fields, a Possible Carcinogen

Dr. Wyde: NTP Toxicology and Carcinogenicity Studies of Cell Phone Radiofrequency Radiation


Spreadsheet of occupations from 2007 exposure database applicable to Dr. Bowman's presentation. This is sourced from the Job Exposure Matrix, which compiled 2317 MF measurements taken on or near workers by 10 studies in the United States, Sweden, New Zealand, Finland, and Italy.

This call was hosted by the CHE-EMF ScienceServ.

On this call, we had two distinguished speaker present on different perspectives of EMF exposures:

  1. Joseph D. Bowman, PhD, of the Engineering and Physical Hazards Branch at the National Institute for Occupational Safety (NIOSH) present Precautionary Strategies to Reduce Worker Exposures to Extremely Low Frequency (ELF) Magnetic Fields, a Possible Carcinogen
  2. Michael Wyde PhD, DABT, of the National Toxicology Program (NTP) presented  Carcinogenesis Studies of Cell Phone Radiofrequency Radiation in Hsd: Sprague Dawley® SD rats (Whole Body Exposure): Report of Partial Findings

Featured Speakers

Dr. Joseph Bowman is a senior research chemist with NIOSH and is currently assessing occupational EMF exposures for the seven-country INTEROCC study of brain cancer. He is also developing NIOSH publications on strategies for managing workplace exposures to lower frequency EMF. Three of his 60 publications have received honorable mentions for NIOSH and CDC awards. Starting with a 1986 epidemiologic study of childhood leukemia risks from electric and magnetic fields in Los Angeles, he has focused on assessing exposure to EMF from power lines, cell phones, and other sources in workplaces and the environment. He received a PhD in physical chemistry from the University of Wisconsin in 1971 and was a Certified Industrial Hygienist from 1982 – 2011.

Dr. Michael Wyde is a toxicologist at the NTP and is overseeing the NTP cell phone studies. He also manages and participates in multidisciplinary teams of NIEHS/NTP scientists to develop research programs to address a broad array of toxicological study needs for chemicals selected for study by the National Toxicology Program. Wyde serves as the project leader for several chemicals including compounds that are used in consumer products, as food additives, as chemical intermediates, and environmental contaminants. He has a particular interest in chemical mixtures and herbal products, as well the application of dose-response modeling to NTP data for use in risk assessment, such as the determination of Benchmark Doses for carcinogenic and non-carcinogenic responses. Wyde received a Ph.D. in toxicology from the University of North Carolina at Chapel Hill.

This call was moderated by Antoinette (Toni) Stein, PhD. Opening remarks were made by Michael Lerner, Commonweal’s President. This call lasted for 60 minutes and was not recorded.
